After throwing a scoreless eighth inning in Friday's 8-0 win, Adams woke up Saturday with pain in his right shoulder, something all too familiar for the 35-year-old. Adams has had two surgeries in the last three years on the same shoulder. Since he arrived in Philadelphia, Adams has been honest about his worries concerning the shoulder, and how he realizes it could end his career.

The Phillies placed Adams on the 15-day disabled list Saturday with rotator cuff inflammation. Fast-rising prospect Ken Giles is coming up to take his place.

"I'm always worried about it, especially considering the history," Adams said. "Any time I felt a little bit of discomfort I got worried. I don't want to try to throw through this right now."

Adams came to the Phillies in the winter of 2012, fresh off shoulder surgery. He had faith in his repaired shoulder and so did Phillies general manager Ruben Amaro Jr. Soon, that faith disappeared, as Adams' 2013 season ended in June. He had another shoulder surgery shortly after and did not return until April 18.

Since then, he has been outstanding. In 19 appearances, Adams only allowed four runs. He quickly became the Phillies' most trusted right-handed reliever outside of closer Jonathan Papelbon. Phillies manager Ryne Sandberg called him a "second closer" Saturday.

Adams said he started feeling the newest pain a week ago and asked for two days off, hoping it would subside. He ended up not pitching for six days before Friday's outing.

"That's probably the most frustrating part. I felt like pitching-wise, I had gotten back to where I was in the past," Adams said. "For something like this to happen and to still be successful, it's a little harder."

Ready for Giles

Giles, meanwhile, represents one of the most-hyped pitching prospects the Phillies have had in recent memory. Giles, 23, began the year in Double-A Reading, where he blew away batters with his 100-mph fastball and improving slider.

He was promoted to Triple-A Lehigh Valley on May 9. In 13 2/3 innings, he's posted a 2.63 ERA, while striking out nine with eight walks.

"He's the next guy in line for us," Sandberg said. "We saw him in the spring and his control has been better and he's made some improvement."

College days

Phillies management wrapped up this year's draft Saturday, keeping in line with a trend that began with their first selection Thursday: picking college players. Twenty-nine of the Phils' 40 draft picks came from the college ranks. Percentage-wise (72.5), that is the most for the Phils in the last 10 years. College players made up 70 percent of the team's selections in 2010.

Phillies scouting director Marti Wolever said Friday the trend was "just a coincidence."
